Hastelloy B-3 Coil (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Coils for chemical and petrochemical processing
As a professional Hastelloy alloy supplier, SEATHER TECHNOLOGY manufactures and supplies high-quality Hastelloy B-3 coil with stable performance and competitive pricing.
HASTELLOY® B-3® alloy (UNS N10675) is a nickel-molybdenum alloy that exhibits exceptionally high resistance to reducing acids, including pure hydrochloric acid, hydrobromic acid, and sulfuric acid. Compared with earlier B-series alloys, Hastelloy B-3 features significantly improved metallurgical stability, which greatly reduces sensitivity to heat-affected zone corrosion and minimizes risks during welding, fabrication, and long-term service.
Hastelloy B-3 coil is produced by rolling Hastelloy B-3 sheet or plate into coils. According to different manufacturing processes, it is available as hot-rolled coil and cold-rolled coil. After flattening, the coils can be further processed into Hastelloy B-3 sheet or plate.
The standard surface finish for cold-rolled Hastelloy B-3 coil is 2B finish, while hot-rolled coil is supplied with a No.1 finish. Other surface finishes can be customized upon request to meet specific application or processing requirements.
With its excellent corrosion resistance, structural stability, and reliable processing performance, Hastelloy B-3 coil is widely used in chemical processing equipment, acid handling systems, heat exchangers, reactors, and other harsh corrosive environments. SEATHER provides strict quality control and complete documentation to ensure consistent product quality and dependable performance.

What is Hastelloy B-3 (UNS N10675)
Alloy B-3 also referred to as the UNS N10675/W.Nr. 2.4600 alloy.
Alloy B-3 is similar to alloy B-2 in terms of resistance to non oxidizing agents, resistance to stress corrosion & pittings, non formation of grain boundry.
Like other nickel alloys (in the mill annealed condition), it is ductile, can be formed and welded, and resists stress corrosion cracking in chloride-bearing solutions.
Also, it is able to withstand fluoride-bearing media and concentrated sulfuric acid, both of which result in damage to zirconium alloys.
Alloy B-3 is widely used in numerous chemical process industry, especially in the construction of reaction vessels for pure, reducing acid service.
B-3 alloy is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and coated electrodes.
